Space Weather Impact on GNSS Performance

lt;b>Vladislav Demyanov, graduated as Ph.D. in Radio wave physics from Irkutsk State University in 2000. He received his Doctor of Science degree in ragio-engineering from Siberian Federal University (Krasnoyarsk city, Russia) in 2011. Now, he is a senior researcher at the Institute of Solar-Terrestrial Physics of Siberian Branch of Russian Academy of Science. Besides he works for both Irkutsk State Transport University and Irkutsk State University as a professor. His research interests include Space Weather impacts on the ionosphere and telecommunication systems (including its transportation applications), GNSS instrumentation for the ionosphere studies.
Yury V. Yasyukevich received his Ph.D. degree in radio physics from Institute of Solar-Terrestrial Physics of Siberian Branch of Russian Academy of Sciences (ISTP SB RAS) in 2009. He works at the ISTP SB RAS as a leading researcher and at Irkutsk state university as an associate professor. His scientific interests include GNSS-ionosphere, space weather impact on GNSS, absolute total electron content. He is a PI of SIMuRG project (http://simurg.iszf.irk.ru).
